Doug, I believe that 94V-0 indicates that the board is self-extinguishing. How about lighting it with a flame, or a glowing PCB trace, and then remove the flame. The board fire should go out. Dave
From: POWELL, DOUG [mailto:doug.pow...@aei.com] Sent: Thursday, June 19, 2003 10:48 AM To: EMC-PSTC (E-mail) Subject: PCB marked for UL 94V-0 Hello group, An interesting question came up about validating printed circuit board raw material. In searching for alternate vendors we provide a spec that V-0 material is required and a UL V-0 stamp be placed on the board. The question is, how do I independently validate the material used, since a vendor could theoretically choose whatever they want and stamp it as V-0? -doug Douglas E.
